大家知道为什么网站建设中基本不用flash了吗?

来源:www.sjkhdkf.com 发布时间:2019/06/28

  Flash确实有很强表现力,能够给人留下深入的印象。但搜索蜘蛛没有眼睛。像Googlebot常常能够读Flash文件,并提取里面的文本和链接,但 疏忽文件的构造和上下文。此外,有些文本的内容在 Flash里面是以图形方式贮存的,而目前 Googlebot 还没有眼睛来算法性地看这些图片,那些文本中的重要关键词就完整被疏忽了。一切这一切意味着搜索蜘蛛会疏忽你的一些文本、内容或者链接,即便你的Flash 内容被收录在搜索引擎的索引中。更糟的是,即便 Googlebot 能够了解一些 Flash 文件,并不是一切的互联网蜘蛛都能够。

  Flash is really expressive and can make a deep impression. But search spiders have no eyes. Google bot, for example, can often read Flash files and extract text and links from them, but neglects the construction and context of files. In addition, some text content is stored graphically in Flash, but at present Google BOT has no eyes to view these pictures algorithmically, and the key words in those texts are completely neglected. All this means that the search spider will neglect some of your text, content or links, even if your Flash content is included in the search engine index. Even worse, even if Google bot can understand some Flash files, not all Internet spiders can.

  Do you know why flash is not used in website construction? - Zhangqiu website construction: http://www.sjkhdkf.com

  看起来Flash是网站优化SEO的大敌了,那么一个页设计师应该怎样做呢?谷歌对此独一的请求是,你必须为 Googlebot 和你的用户显现完整一样的东西。假如不这样做,你的网站会被谷歌算法疑心为可疑网站。这个简单的规则掩盖了大量的例子,包括假装 (cloaking),JavaScript 重定向,躲藏文本及桥页(Doorway pages)。

  It seems that Flash is the enemy of website optimization SEO, so what should a page designer do? Google's only request for this is that you have to show Google BOT and your users exactly the same thing. If you don't, your site will be suspected of being a suspicious site by Google Algorithms. This simple rule masks a number of examples, including cloaking, JavaScript redirection, and Doorway pages.

  以下是谷歌的工程师们群策群力而给出的更适用的倡议:

  Here's a more practical proposal from Google's engineers.

  1. 尽量只在需求的中央才用Flash。许多富媒体(Rich Media)网站,例如谷歌的 YouTube,只为富媒体运用 Flash,而依赖于HTML 来表达内容和导航。您也能够这样做,只对网页基调和富媒体运用 flash,但不用它来表达内容和导航。这样做除了使你的站点对 Googlebot 友好外,也使你的网站便于更多的观众阅读,其中包括,例如,运用屏幕阅读器的盲人,运用古老的或不规范的阅读器的用户,以及运用有限的低带宽衔接,如手机 或 PDA 的用户。一个额外益处是,你的网站访问者能够有效地运用书签,并能够把你的网页地址经过电子邮件传给他们的朋友。

  1. Try to use Flash only in the middle of the demand. Many Rich Media sites, such as Google's YouTube, use Flash only for rich media and rely on HTML to express content and navigation. You can also do this by using flash only for the keynote and rich media, but not for content and navigation. In addition to making your site Google-friendly, it will also make your site more accessible to more audiences, including, for example, blind people using screen readers, users using old or non-standard readers, and users using limited low-bandwidth connectivity, such as mobile phones or PDAs. One additional benefit is that your site visitors can effectively use bookmarks and can e-mail your web address to their friends.

  2. SIFR:一些网站应用 Flash 以使阅读器能显现大标题、重点提示、或其他用户可能没有装置在他们的计算机上的字体文本内容。采用象 SIFR 那样的技术仍允许不能看 Flash 的读者能读页面,由于内容和导航其实是在 HTML 页面上。阅读器所做的只是对一个嵌入 Flash 对象的显现。

  2. SIFR: Some websites use Flash to enable readers to display headlines, highlights, or other font text content that users may not have installed on their computers. Technology like SIFR still allows readers who cannot see Flash to read pages, because content and navigation are actually on HTML pages. What the reader does is display an embedded Flash object.

  3. 无flash版本:我们通常见到的一种Flash的运用是,Flash 被用作首页的闪屏,在flash上有一些到网站其他网页的HTML内容。在这种状况下,在首页上要确保有一个普通HTML链接到一个非 flash 页。在该非 flash 页上你的用户能够阅读整个网站,而不需求 flash。 所倡议企业在针对做企业网站建立的时分尽量还是少用Flash,做Flash的优化比拟费事。

  3. Flash-Free Version: One of the most common Flash applications we see is that Flash is used as a flash screen on the home page, with some HTML content on the flash to other pages of the website. In this case, make sure that there is a normal HTML link on the home page to a non-flash page. On this non-flash page, your users can read the entire site without requiring flash. It is advocated that enterprises should use Flash as little as possible when building enterprise websites, and it is difficult to optimize Flash.
